5.2 IR Control

By using IR & HDBaseT transmission technology, MHD44TP has some functions as

follows:

1) Control far-end output device from local.

2) Control local input/output device remotely.

3) Control MHD44TP locally/remotely.

MHD44TP can be controlled by its built-in IR receiver or through the IR EYE port by

connecting with extended IR receiver, or even can be controlled remotely by a far-end

IR device through the twisted pair.

5.2.1 Usage of IR Remote

5.2.2 IR Operations

1) IR Matrix Switching

The 4 “IR OUT” ports make up a 4x4 IR matrix with the “IR IN” ports of the far-end

receivers. See as below:

Input channels, range from 1~4, IR signal switched

following HDMI signal correspondingly.

Menu buttons, AV and ALL buttons have the same

function as the front panel. THROUGH: To transfer

the signals directly to the corresponding output

channels

Example: Press “3”, “THROUGH”, the result will be IN

3OUT 3. Press “ALL”, “THROUGH”, the result will

be: 11, 22, 33, 44

Output channels, range from 1~4.

Each channel has 1 IR IN, 1 COAX, 1 HDBaseT, 1

RS232, and 1 AUDIO outputs, and channel No.1 &

No.2 has 1 HDMI output.

Standby button, press it to enter in standby mode.

Control Local Devices or MHD44TP Remotely

HDBaseT Matrix Switcher 4x4

PTN Electronics Limited 12 www.PTN-electronics.com

The IR signal is received from corresponding remote controller, then transferred to

HDBaseT receiver, then to corresponding zone of MHD44TP through the twisted pair,

finally transferred to IR OUT port and received by controlled device.

Switching Operation:

a) Sending command, reference to 5.3 RS232 Control: [x1]R[x2].

x1: Corresponding to the 4 IR OUT ports of MHD44TP, The IR emitter connected to

this port can be placed at IR receiving area of output device or MHD44TP itself.

x2: Corresponding to the zone (receive IR signal from HDBaseT receiver with IR IN

port connects with IR receiver) number of MHD44TP.

E.g.: Command “3R2.” means to transfer IR signal received from zone 2 to IR OUT

port 3.

b) Using IR remote: Input channelbutton IROutput channel

Input channel: the 4 INPUTS buttons, corresponding to the 4 IR OUT ports of

MHD44TP.

Output channel: the 4 OUTPUTS buttons, corresponding to the zone (receive IR

signal from HDBaseT receiver with IR IN port connects to IR receiver) number of

MHD44TP.

E.g.: Press buttons “3”, “IR”, “1” in order, “3” in OUTPUTS area, “1” in INPUTS area,

to transfer IR signal received from zone 3 to IR OUT port 1.

Note: When switch all the 4 IR input signal channels to a same IR out channel,

it is not able to control the controlled device(s) at the same time.

2) IR Carrier Enforcing

a) Only if the IR receiver connected with HDBaseT receiver is with IR carrier, the

received IR signal can be transferred to IR OUT port of MHD44TP.

b) Only if the IR receiver connected with IR ALL IN port of MHD44TP is with IR carrier,

the received IR signal can be transferred to IR OUT port of MHD44TP.

If the IR receiver connected with HDBaseT receiver or IR ALL IN port of MHD44TP is

not with IR carrier, you need to send the command “%0901.”, and then you are able

to transfer the IR signal to IR OUT port.

3) IR Settings

When need to control a remote displayer from local, the IR receiver used must be with

IR carrier. The IR signal is transferred to the corresponding zone connected with the

HDBaseT receiver which is connected with the IR emitter. When the IR receiver is

connected to IR ALL IN port, the IR signal can be finally transferred to all the 4 IR

emitters connected with HDBaseT receivers.

As the figure below:

Control Remote Displayer from Local

HDBaseT Matrix Switcher 4x4

PTN Electronics Limited 14 www.PTN-electronics.com

4) Controlled by a Third-party IR Control Device

Use the included IR converting cable (see as below), connect the red end to IR input

port of MHD44TP, the black end to IR output port of the third-party control device. Then

the IR signal is able to be transmitted via the twisted pair, and finally gets to remote

output device.

5.3 RS232 Control

5.3.1 RS232 Commands

Through the RS232 communication port, user can control a far-end device whose

bound rate is 2400, 4800, 9600, 19200, 38400, 57600 or 115200. Default setting of

MHD44TP: bound rate is 9600, data bit is 8, stop bit is 1 and parity bit is none.

Value = 1,2,3,4,5,A,B,C,D,E,F,G or H

The value of Y is defined into the following

meanings (in a given baud rate depended by the

value of X):

a. Y = 1, 2, 3 or 4, send this command to the

corresponding HDBaseT receiver to control

far-end device.

b. Y = 5, send this command to all HDBaseT

receivers to control all far-end devices.

c. Y = A, B, C or D

d. Y = E, F, G or H

For items c or d, send this command, it will be

saved to MHD44TP but taken without action to

corresponding HDBaseT receiver. And its

command function will be effective almost at the

same time when you send the command PWON

(for item c) or PWOFF (for item d).

Note:

A & E are for port 1.

B & F are for port 2.

C & G are for port 3.

D & H are for port 4.

② X is for bound rate (Value ranges from 1 to 7, 1

is for 2400, 2 for 4800, 3 for 9600, 4 for 19200, 5

for 38400, 6 for 57600 and 7 for 115200)

③ ***** is for data (max 48 Byte)

④ The symbol “.” is the end of one command. If

there are some symbols of “.” in one command,

this case is allowed and the last one is the end.

Note: 1. Please disconnect all the twisted pairs before sending command

EDIDUpgrade[X].

2. In above commands, “[”and “]” are symbols for easy reading and do not need

to be typed in actual operation.

3. Please remember to end the commands with the ending symbols “.” and “;”.

4. Type the command carefully, it is case-sensitive.
